Lord Viratus appears in Skirmish at Darkstar where he pilots a stolen Tundra H/Y Mk IX Mantis, and spawns at exactly 12 minutes and 13 seconds into the game. Killing him is worth 150 points. He is the second legendary boss to spawn in the map, the first being Endurance-of-Will. He is the only boss that spawns in the Crossroads.
